The invention belongs to the field of medicaments and in particular relates to tablets containing mosapride citrate and a preparation method thereof. Because the mosapride citrate is almost insoluble, defects of slow dissolution and low in-vitro and in-vivo bioavailability are present in the mosapride citrate tablets prepared by the common method. In order to improve the dissolution and bioavailability of the mosapride citrate, the invention provides dispersible tablets containing the mosapride citrate and a preparation method thereof. The prepared mosapride citrate dispersible tablets have high dissolution speed and low dissolution difference. The accumulated dissolution in five minutes is close to 100 percent, and the dispersible tablets are almost dissolved completely.
